Does any diecast gain or even retain value?.
I think JL's day has yet to come,there are some real nice pieces that other companies won't attempt to do or if they do,can't get it right.
So I believe at some point their value will rise dramatically,they may never reach the level of original toppers or redline HW's but may come close.
One of the major reasons it will happen is strictly because of the production numbers.
Even some treasure hunts have runs of 50,000 or more,granted there are many more HW collectors worldwide that still is an awfully high number for a collectible.
Both JL and Greenlight will both,in the future be very sought after diecast but since I don't really care about value at this point,I'll just enjoy them for the works of art they are.Long after I'm gone and my cars are passed down,someone will reap the monetary rewards and someone will get one hell of a diecast collection but until then I love this hobby and will continue to buy what I like.
It started on christmas of 1968 with 4 hot wheels and has grown to just under 10,000 pieces today and back then it was spectraflame redlines but today JL has taken over top spot,from 1996-2007 my jl addiction has only gotten stronger.
